[0026] Reference Figure 1The preferred embodiment of the utility model provides a mortar joint compacting device, including a cabin 1, a compacting wheel 2, a sliding wheel 3 and a handle 4, the handle 4 is connected to one side of the cabin 1, the compacting wheel 2 and the sliding wheel 3 are both connected to the cabin 1, the compacting wheel 2 and the handle 4 are arranged at intervals, and the rolling direction of the compacting wheel 2 is consistent with the direction of pulling the handle 4, the sliding wheel 3 is located between the compacting wheel 2 and the handle 4, and the rotation directions of the compacting wheel 2 and the sliding wheel 3 are consistent, the compacting wheel 2 is detachably connected to the cabin 1, the cabin 1 is a groove type, which includes an opening 11, the compacting wheel 2 and the sliding wheel 3 are both located in the cabin 1, and both extend out of the opening 11. The compacting wheel 2 is driven forward by the sliding wheel 3, and the mortar joint is rolled by the surface curvature of the compacting wheel 2, so that the surface of the filler in the mortar joint is flat and dense, and a U-shaped joint is formed. Since the compacting wheel 2 is detachably connected to the cabin 1, compacting wheels 2 of different sizes can be replaced for mortar joints of different widths, the difficulty of U-shaped joint formation is reduced, and the quality of the obtained U-shaped joint is good, thereby reducing the construction difficulty and improving the construction quality. After completing a mortar joint construction, the compacting wheel 2 can be removed for cleaning to prevent the mortar from sticking to the compacting wheel 2, resulting in an uneven surface of the compacting wheel 2 and affecting the forming quality of the U-shaped joint.
[0027] See also Figure 4 The cabin 1 is provided with a notch 12, and the compacting wheel 2 extends out of the notch 12. The notch 12 enables a compacting wheel 2 of a larger size to fit with the cabin 1, and the cabin 1 does not restrict the rolling of the compacting wheel 2, thereby improving the adaptability of the device.
[0028] In this embodiment, the cabin body 1 is welded from stainless steel plates. Stainless steel is strong and durable, and welding is easy to manufacture.
[0029] The sliding wheel 3 is detachably connected to the cabin 1, and the size of the sliding wheel 3 is replaceable. Compacting wheels 2 of different sizes have different weights. Therefore, for compacting wheels 2 of different weights, sliding wheels 3 of different sizes are used to adapt to them to avoid the sliding wheel 3 being too small and the compacting wheel 2 being too large, which causes the user to use a lot of force to make the sliding wheel 3 drive the compacting wheel 2 forward.
[0030] The compacting wheel 2 is a solid stainless steel ball with a heavy weight, which is conducive to compacting the filling material in the mortar joint more densely and improving the construction quality.
[0031] See 1 and Figure 2 The cabin 1 is connected to the compacting wheel 2 through a first pin shaft 21. The first pin shaft 21 is penetrated through the compacting wheel 2, and the compacting wheel 2 is rotatably connected to the first pin shaft 21. The two ends of the first pin shaft 21 are detachably connected to the two side walls of the cabin 1 respectively. The first pin shaft 21 works reliably and is easy to disassemble, which facilitates the disassembly and assembly of the compacting wheel 2 and the sliding wheel 3.
[0032] See also Figure 4 and Figure 5In this embodiment, first punching holes 13 are provided on both sides of the cabin body 1, and the two ends of the first pin shaft 21 are respectively penetrated through the two first punching holes 13. The mortar joint tightening device also includes a first cotter pin 5. The first pin shaft 21 includes a first head portion 211 and a first tail portion 212. The first tail portion 212 is provided with a first pin hole 213. The first cotter pin 5 is inserted into the first pin hole 213 to limit the first pin shaft 21 from escaping from the first punching hole 13. The above arrangement ensures the stability of the connection between the first pin shaft 21 and the cabin body 1, and facilitates the disassembly and assembly of the first pin shaft 21 and the cabin body 1.
[0033] See also Figure 3 There are two sliding wheels 3, and the two sliding wheels 3 can provide support to prevent the device from tipping over. A second pin shaft 31 is connected between the two sliding wheels 3, and the second pin shaft 31 is penetrated by the two sliding wheels 3, and the two sliding wheels 3 are rotatably connected to the second pin shaft 31. The mortar joint tightening device also includes a second cotter pin 6, and the second pin shaft 31 includes a second head 311 and a second tail 312. The second tail 312 is provided with a second pin hole 313, and the second cotter pin 6 is inserted into the second pin hole 313 to limit the sliding wheel 3 from escaping from the second pin shaft 31. The second pin shaft 31 is located below the cabin 1. Specifically, both ends of the second pin shaft 31 abut against the edge of the opening 11 of the cabin 1. The second pin shaft 31 is connected to a fixing rod 32, and the fixing rod 32 is detachably connected to the cabin body 1. Specifically, the second pin shaft 31 is vertically connected to the fixing rod 32, one end of the fixing rod 32 is located between the two sliding wheels 3, and the other end is detachably connected to the cabin body 1. To replace the sliding wheel 3, it is only necessary to disassemble and assemble the fixing rod 32 from the cabin body 1. The sliding wheel 3 is easy to replace and convenient to use.
[0034] The second pin shaft 31 is welded to the fixing rod 32 , and the connection between the two is firm and more durable; the fixing rod 32 is screwed to the cabin body 1 , and the screw connection can ensure that the connection between the two is firm and can also facilitate disassembly and assembly.
[0035] See also Figure 4 and Figure 6 In this embodiment, a second punching hole 14 is provided on the bottom surface of the cabin body 1, and the end of the fixing rod 32 away from the second pin shaft 31 is penetrated by the second punching hole 14, and the end of the fixing rod 32 away from the second pin shaft 31 is provided with a thread 321, and the mortar joint tightening device also includes a wing nut 7, and the wing nut 7 is screwed with the thread 321 to limit the fixing rod 32 from escaping from the second punching hole 14. The above arrangement ensures the stability of the connection between the fixing rod 32 and the cabin body 1, and the wing nut 7 is easy to disassemble and assemble, thereby facilitating the disassembly and assembly of the fixing rod 32 and the cabin body 1.
[0036] The handle 4 includes a first connecting rod 41 and a second connecting rod 42 connected at the ends. The end of the first connecting rod 41 away from the second connecting rod 42 is connected to the cabin 1, and the first connecting rod 41 and the second connecting rod 42 are arranged at an angle. The second connecting rod 42 is arranged obliquely. When the user pulls the second connecting rod 42, the force applied to the second connecting rod 42 can be divided into a horizontal direction and a vertical direction. The horizontal force can drive the device to move horizontally, and the vertical force can apply pressure to the compacting wheel 2, so that the U-shaped seam pressed out by the compacting wheel 2 has a better quality. The force applied by the user is applied in two aspects, which is convenient for use.
[0037] In this embodiment, the included angle between the first connecting rod 41 and the second connecting rod 42 is 140°, which can be maximized for ease of use.
[0038] The first connecting rod 41 and the second connecting rod 42 are integrally formed. Specifically, the first connecting rod 41 and the second connecting rod 42 are formed by bending the same steel material, which is easy to manufacture, and the first connecting rod 41 and the second connecting rod 42 are firmly connected.
[0039] An anti-drop ring 43 is provided at one end of the second connecting rod 42 away from the cabin body 1. When in use, the user can hold the anti-drop ring 43 to prevent the ring from slipping out of the hand, which is convenient for use.
[0040] In this embodiment, the anti-drop ring 43 is welded to the second connecting rod 42, and the two are firmly connected.
